A simple shell script I wrote to learn more about creating command line tools. It works by converting the video to images using ffmpeg and then converting those images into an animated gif with imagemagick.
Of course you could always do it in a oneliner:
ffmpeg -i input.mp4 -vf scale=600:-1 -r 5 -f image2pipe -vcodec ppm - | convert - gif:- | convert -layers Optimize - output.gif
But then you miss out on
- Dependency checking
- Usage and help information
- Nice error notifications
Usage:
vidtogif [-r <integer> -w <integer> -h <integer> -u -v] input.mp4 output.gif
Options:
-r: Framerate per second <integer>
-w: Set max width <integer>
-h: Set max height <integer>
-u: Print usage information
-v: Version
Example:
Example: vidtogif -r 10 -w 600 input.mp4 output.gif
Here's an example of a gif created with vidtogif:
